Important: Connecting rod bearings are the precision insert type and do not use shims for adjustments. Do not file connecting rods or rod caps. If the clearances are found to be excessive, a new bearing will be required. Service bearings are available in the following sizes:

1. Remove the oil pan. Refer to Oil Pan Replacement .
2. Remove the oil pump. Refer to Oil Pump Replacement .

Important: Place numbers on the connecting rods and the connection rod caps. The connecting rod caps must be assembled with the original connecting rods.




3. Remove the connecting rod nuts.
4. Remove the connecting rod cap and the bearings.
5. Keep the bearings with the original connecting rod and the connecting rod cap for re-assembly.
6. Wipe the oil from the bearings and the crankpins.
7. Inspect the bearings for excessive wear or damage.
8. Measure the crankpin for out-of-round and taper with a micrometer.
9. If not within specifications, replace or recondition the crankshaft.
10. If installing new bearings, determine new bearing size from the maximum crankpin diameter.
11. Measure the bearing clearance, using gauging plastic.
12. Place a piece of gauging plastic the full width of the bearing onto the crankpin.
13. The plastic gauge should be positioned in the middle of the bearing. The bearing is thickest in the center and the bearing clearance must be measured at this location.
14. Install the connecting rod cap with the bearing onto the connecting rod.
15. Install the connecting rod nuts.

Tighten
Tighten the connecting rod nuts evenly to 27 N·m (20 lb ft) plus an additional 55 degrees using the J 36660-A .

Notice: Do not turn the crankshaft with the gauging plastic installed or the accuracy of the measurement will be affected.

16. Remove the connecting rod nuts and the connecting rod cap.

The gauging plastic will be found adhering to either the connecting rod cap or crankshaft journal. Leave the gauging plastic in place to measure it.

17. Measure the gauging plastic at its widest, using the scale provided with the gauging plastic.
18. If the clearance is greater than specified, select an undersize bearing and re-measure the clearance.
19. If the clearance cannot be brought to specifications, regrind the crankpin. If the crankpin is already at maximum undersize, replace the crankshaft.
20. Remove the gauging plastic.

1. Coat the inside surface of the bearings with the engine oil.
2. Install the connecting rod cap and the bearings.
3. Install the connecting rod nuts.

Tighten
Tighten the connecting rod nuts evenly to 27 N·m (20 lb ft) plus an additional 55 degrees.

4. Measure the connecting rod side clearance as follows:

4.1.	When all the connecting rod bearings have been installed, tap each connecting rod lightly parallel to the crankpin to make sure they have clearance.

4.2.	Measure the side clearance between the connecting rod caps using a feeler gauge or dial indicator.

4.3.	The rod side clearance should be 0.16 to 0.35 mm (0.006 to 0.014 in).

5. Install the oil pump. Refer to Oil Pump Replacement .
6. Install the oil pan. Refer to Oil Pan Replacement .
